Method and Apparatus for Assisting Terminal in Measuring

1. A method for assisting a user equipment (UE) in measuring, the method comprising: detecting, by the UE, a discovery reference signal (DRS) sent by a second base station while the UE is served by a first base station, wherein the DRS comprises identity information of a cell formed by the second base station, frequency information of the second base station, and frequency domain, time domain and sequence information of a radio resource management reference signal (RRM-RS); receiving, by the UE after detecting the DRS, the RRM-RS sent by the second base station without any intervening communication between the UE and the second base station; performing, by the UE, measurement according to the RRM-RS to obtain a measurement result; and reporting, by the UE, the measurement result to the first base station.

2. The method according to claim 1 , wherein the RRM-RS is a channel state information reference signal (CSI-RS) or a common reference signal (CRS).

3. The method according to claim 1 , the DRS comprises a synchronization signal.

4. The method according to claim 1 , wherein receiving the RRM-RS comprises: directly starting to receive the RRM-RS after detecting the DRS; or starting to receive the RRM-RS after detecting the DRS and after waiting for a first predetermined time; or starting to receive the RRM-RS according to a received control instruction, wherein the control instruction is used to instruct the UE to receive the RRM-RS.

5. The method according to claim 1 , wherein when the UE supports carrier aggregation, and after sending the measurement result to the first base station, the method further comprises: activating, by the UE and after receiving an activation instruction sent by the first base station, a carrier corresponding to the second base station.

6. An apparatus comprising a processor configured to connect with a non-transitory computer readable storage medium, wherein the non-transitory computer readable storage medium stores a program, and when the program is executed by the processor, at least the following operations are performed: detecting a discovery reference signal (DRS) sent by a second base station while the apparatus is served by a first base station, wherein the DRS comprises identity information of a cell formed by the second base station, frequency information of the second base station, and frequency domain, time domain and sequence information of a radio resource management reference signal (RRM-RS); receiving, after detecting the DRS, the RRM-RS sent by the second base station without any intervening communication between the UE and the second base station; performing measurement according to the RRM-RS to obtain a measurement result; and reporting the measurement result to the first base station.

7. The apparatus according to claim 6 , wherein the RRM-RS is a channel state information reference signal (CSI-RS) or a common reference signal (CRS).

8. The apparatus according to claim 6 , wherein the DRS comprises a synchronization signal.

9. The apparatus according to claim 6 , wherein receiving the RRM-RS comprises: directly starting to receive the RRM-RS after detecting the DRS; or starting to receive the RRM-RS after detecting the DRS and after waiting for a first predetermined time; or starting to receive the RRM-RS according to a received control instruction, wherein the control instruction is used to instruct the apparatus to receive the RRM-RS.

10. The apparatus according to claim 6 , wherein when the program is executed by the processor, the following operation is further performed: activating, after receiving an activation instruction sent by the first base station, a carrier corresponding to the second base station.

11. A device for assisting a terminal in measuring, comprising a processor configured to connect with a non-transitory computer readable storage medium, wherein the non-transitory computer readable storage medium stores a program, and when the program is executed by the processor, at least the following operations are performed: periodically sending a discovery reference signal (DRS) to the terminal, wherein the DRS comprises identity information of a cell formed by the device, frequency information of the device, and frequency domain, time domain and sequence information of a radio resource management reference signal (RRM-RS), and wherein the device is a second device sending the DRS to the terminal while the terminal is served by a first device; and sending the RRM-RS to the terminal without any intervening communication between the terminal and the second device, wherein the RRM-RS is used by the terminal to perform measurement on the second device after detecting the DRS.

12. The device according to claim 11 , wherein the RRM-RS is a channel state information reference signal (CSI-RS) or a common reference signal (CRS); and the DRS comprises a synchronization signal.

13. A non-transitory computer-readable storage medium, comprising a program, wherein when the program is executed by a processor, at least the following operations are performed: detecting a discovery reference signal (DRS) sent by a second base station while the apparatus is served by a first base station, wherein the DRS comprises identity information of a cell formed by the second base station, frequency information of the second base station, and frequency domain, time domain and sequence information of a radio resource management reference signal (RRM-RS); receiving, after detecting the DRS, the RRM-RS sent by the second base station without any intervening communication between the UE and the second base station; performing measurement according to the RRM-RS to obtain a measurement result; and reporting the measurement result to the first base station.

14. The non-transitory computer-readable storage medium according to claim 13 , wherein the RRM-RS is a channel state information reference signal (CSI-RS) or a common reference signal (CRS).

15. The non-transitory computer-readable storage medium according to claim 13 , the DRS comprises a synchronization signal.

16. The non-transitory computer-readable storage medium according to claim 13 , wherein when the program is executed by the processor, the following operation is further performed: activating, after receiving an activation instruction sent by the first base station, a carrier corresponding to the second base station.
